Abstract
A switching device is provided for electrical switchgear, particularly contactors. The switching device includes a step-shaped, bowed current lead with a contact portion cooperating with a contact portion of a switch bridge. The switching device also includes a U-shaped arc chute and a fastening bolt. The arc chute surrounds the contact portion with an air gap so that the electrical connection is made solely via the fastening bolt. The edge portions of the arc chute are set back in the area of the contact portion so that the contact portion of the contact bridge cannot come in contact with the arc chute even though the contact bridge may be obliquely positioned.
